MAL'IING APPARATUS.

To all whom it may concern:

Be 1t known that I, WILLIAM H. PRINZ,

a citizen of the United States, residing at (llhicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Malting Apparatus, of which the following is aspecification, reference being had to the accompanying drawings.

My invention relates to apparatus for malting grain, and particularly toapparatus involving a rotary drum divided into a plurality of maltcompartments, with means for supplying attemperated air to the grain inthe compartments, which generically forms the subject matter of myapplication for patent of even date herewith, Serial Number 170,414. Theapparatus described in my said application, specifically considered,involves the application of attemperated air to the grain in the maltcompartments of a sectional perforated drum, by pressure, the air beingintroduced into the drum through conduits disposed axially in themalting compartments and passing out through the shell of the drum intothe malting room.

My present invention has for its object to provide means for supplyingattemperated air to the malt in a drum having the construction describedin my said application,

by suction, instead of by pressure, so that the air enters the maltingcompartments through the perforations in the shell thereof, and thencepasses through the malt from circumference to center. I accomplish thisobject as hereinafter described and as illustrated in the drawings.

What I regard as new is set forth in the claims.

In the drawings, Figure 1 is a longitudinal sectional view of the drumand the conduits connected therewith; Fig. 2 is a horizontal sectionalView of the attemperator floor; and Fig. 3 is a horizontal sectionalView of the malting room.

In my application of even date herewith, above referred to, I havedescribed in detail the construction of my improved sectional drum; andtherefore I deem it unnecessary to describe said drum specificallyherein, except in so far as may be necessary to a full understanding ofits general construction.

Referring to the drawings, A-B indicate the malting compartments of thedrum, and C an intermediate compartment. The

Specification of Letters Patent.

Application filed August 22, 1903.

Patented May 2%, 1910. Serial no. 170,415.

malting compartments A-B are adapted to rotate in unison, beingconnected rigidly together by plates 1, connected with heads 23,respectively, at the inner ends of the drum sections forming thecompartments 4 5 indicate the heads at the outer ends of thecompartments A -B, respectively. The heads 2 8, 4-5 are imperforate,except at the axis of the drum. The heads 2-4 of the compartment A arejoined by a perforated shell or casing 6, while the heads 8-5 of thecompartment B are connected by a perforated shell or casing 7.

The heads 23 are connected by an imperforate shell or casing 8, which isnonrotary, being connected at its lower end to a flue or conduit 9connected with an air tunnel l0.

1l-12 indicate perforated conduits ar ranged axially in the compartmentsAB, respectively, their ends being secured to the heads of theirrespective compartments.

13-14 indicate external extensions of the conduits 1l12, respectively,which extensions are joined to stationary conduits 15-- 16,respectively, which comn'iunicate through conduits 1718, respectively,with tunnels 1920, respectively. By this construction, by suctionapplied to the tunnels 1920, air within the compartments A-B may beexhausted through the conduits 1112; also, by suction applied to thetunnel 10, air in the compartments AB may be exhausted throughcompartment C. The conduits 9, l7 and 18 are provided with valves2l-22-- 28, respectively, so that the flow of air through them may beregulated.

2 1- indicates a manhole through the casing 18, which is closed by asuitable cover. Similarly, the shells G-7 of the compartments AB areprovided with suitable openings closed ordinarily by covers 2526.

21-28 indicate conveyers for conducting off the malt discharged from thedrum. The drum is mounted upon suitable supporting rollers, not shown,carried by supports 29 30, respectively, shown in my application abovereferred to, and is driven by any suitable gearing, such as worms 81 andworm wheels 32, also fully described in my said application.

D indicates the malting room, in which a series of drums are arrangedside by side, as shown in Fig. 3, said drums all being in communicationwith the different tunnels 19, 10, 20.

E indicates the atteinperator room, and F a sectional attemperatortherein, which is preferably of the construction described in my saidapplication.

33 indicates a series of openings in the floor of the attemperator room,to aflord communication between said room and the malting room D. \Vherethe attemperator room is immediately above the malting room, theaassages 33 are simply holes cut in the floor, but they may be extendedconduits, if necessary.

3-l indicates openings in the wall of the attemperator room for theadmission of external air thereto. It will be observed that theattemperator F is between the openings 34 and the passages 33, so thatair entering the attemperator room through the openings 3% must passthrough the attemperator before entering the malting room through thepassages 33.

G indicates what may be termed the exhaustroom, since it contains thefan 35 by which air is exhausted from the drums.

36-37 38 indicate flues affording communication between the room G andthe tunnels 20, 10, 19, respectively, as shown in Fig. 2.

l-l indicates the steep-tank room, which is preferably separated fromthe rooms EGr by partitions 39l0, respectively.

etl42i3 indicate valves in the flues 363T38, respectively. Said valvesare of the ordinary butterfly type, and serve to regulate the flow ofair through their respective flues.

It will be understood that the fan 35 discharges into the open air, itsinlet end being connected with the exhaust room Gr. By thisconstruction, by operating the fan 35, air is exhausted from the roomGT, thereby creating suction through the flues 3637-38 and exhaustingthe air in tunnels 19, 10, 20. The result is that air is exhausted fromthe compartments ABC, causing a flow of air into the compartments ABthrough the perforated walls thereof, the air entering the saidcompartments from the malting room, which continuously receives a supplyof fresh air from the attemperator room through the passage 33. Sincethe suction is applied to the compartments A-B by means of the conduits1112, which are con nected at both ends to the suction apparatus, itwill be seen that suction is applied equally throughout the length ofthe malting compartments ih B and that the air flows in the samedirection through the malt in the different compartments; consequentlythe grain therein is uniformly subjected to the action of the fresh air.

I wish it to be understood that my invention is not restricted to thespecific details of the construction described, except in so far as theyare particularly claimed.
